Hello mario.contestabile,

There are not any customer facing documents that explain Selective Cache Mirroring other than what has been provided already.  Here is some additional information, however I can’t send you the link as it is for support only.

Selective Mirroring, available with Enginuity 5772.83.75 and later, changes the way that mirrored cache works for Read I/O profiles. This change improves bandwidth up to 33% for FBA devices.

Hi,

Thanks for your question about selective cache mirroring. I wasn’t able to find any specific documents for it, but here are all of the whitepapers and the performance ones may still help. https://dell.to/3aDmRzq

 

 

 

 

Let us know if you have any additional questions.

Hi,

 

thanks for your reply and for the materials. Indeed the question is not answered snce is regarding only the selective cache mirroring PowerMax feature and it's a topic of a storage IE exam  too: that's why I wanted to read something about it,
